A Kurdish militant group has claimed responsibility for the large explosion on Sunday in Ankara capital, that killed at least 37 and wounded 125 people, according to a statement on the group’s website.

The Kurdistan Freedom Hawks (TAK) claimed the "vengeful action" was in response to government security operations in the mainly Kurdish southeast, underway since July.

In their statement, the group, an offshoot of the banned Kurdistan Workers Party (PKK), named one of the bombers as 24-year-old Seher Demir.

Demir's involvement in the explosion was also confirmed by a written statement from the Turkish interior ministry, CNN reported.

Turkey's Health Minister Mehmet Muezzinoglu said 19 of those wounded were in serious condition. He added that 30 of the fatalities were killed at the scene of the explosion, while the other four died later at nearby hospitals.

The explosion was caused by a powerful car bomb and targeted civilians at a bus stop, Interior Minister Efkan Ala said in a statement Sunday.

As of Monday evening authorities had detained 11 people in connection with the bombing, Turkey's prime minister Ahmet Davutoglu said.

According to the Associated Press, he said earlier this week it is believed that the attacks were carried out by Kurdish rebels and that DNA tests were underway to identify the two bombers.
